China has closed 13 cities due to coronavirus, and snakes are called the possible cause of the epidemic

China has closed 13 cities due to coronavirus, and snakes are called the possible cause of the epidemic 92

For several days now, the whole world has been closely watching the news about the new coronavirus from China. Just a few days ago, we informed you about the 2019-nCoV outbreak in Wuhan, but things are changing every day. New data on the number of infected not only in China, but also in other countries of the world come almost every hour. The World Health Organization (WHO) held a second emergency meeting during which it was decided not to declare a state of emergency due to an outbreak of coronavirus. Meanwhile, Chinese scientists conducted a study according to which snakes are the source of coronavirus. However, the work raised questions from a large number of scientists.

WHO experts decide not to declare a global emergency

What is happening in China and the world right now?

As he writes in his Twitter  account, WHO Director-General Dr. T. A. Gebreyesus, experts and scientists are serious about what is happening in China. On January 22 and 23, emergency meetings of the WHO took place during which the decision to declare an emergency was not made, since so far little is known about 2019-nCoV. Emergency is observed in China, but now we are not talking about a global threat. Previously, WHO specialists were sent to China to collaborate with Chinese scientists and collect additional information.

Meanwhile, the Chinese government quarantined the city of Wuhan, which is considered the epicenter of a coronavirus outbreak. At least 11 million people live in Wuhan, all flights to and from abroad are canceled, residents are forbidden to leave, public transport has stopped and panic has begun in the city, as frightened residents empty store shelves. Already in the evening of January 23, it became known about the second closed city of Huanggang, with a population of 7.5 million people. As Tailymail writes, stations in the third city of Echzhou are closed, and public transport is restricted in Xiantao and Chibi. The Chinese authorities also officially canceled the celebration of the New Year on the lunar calendar. Traditionally, during the New Year holidays, millions of Chinese citizens travel around the country and abroad to meet with relatives.

On the morning of January 24, citing local media, Interfax reported the closure, in addition to Wuhan, of another 12 cities. So far, the exact list has not been disclosed.

Currently, the officially numbers show 25 dead and more than 800 infected. Infections were reported by authorities in Singapore, Japan, Vietnam, the United States, Saudi Arabia, Thailand and Macau. There are coronavirus suspected patients in some European countries. Professor Neil Ferguson, an expert in mathematical biology at Imperial College in London, told The sun reporters, that the mortality from a new strain of coronavirus is “about the same as during the Spanish flu epidemic in 1918,” and the maximum number of infected can reach 10 thousand people.

What exactly is known about the new coronavirus?

Doctors have confirmed that 2019-nCoV is much more contagious than previously thought, and can be transmitted by a third party with a simple cough or sneeze. Third-party transmission of the infection means that the virus has overcome the protective barrier and is no longer transmitted through animals. An airborne type of virus transmission, however, may not be the only one. During the second emergency meeting, WHO experts said that very little is known about the virus at the moment, including with regard to distribution methods. Concerns about the rapid mutation of 2019-nCoV have previously been expressed by Chinese officials, but there is currently no confirmation of this.

Can snakes be a source of coronavirus?

Scientists are trying to identify animals, which probably led to an epidemic. In a controversial study published on the evening of January 22 in a journal Journal of Medical Virology, a team of researchers from China claims that snakes became the cause of the outbreak of coronavirus. Scientists analyzed and compared the genetic sequences of 2019-nCoV and all other known coronaviruses. According to researchers, the accumulation of snakes in one place could be the most likely reservoir of wild animals for the new coronavirus. But many scientists are skeptical of this statement.

Researchers doubt that snakes are the source of coronavirus

As Nature writes, at the moment there is no evidence that such viruses can infect species other than mammals and birds. Science does not know a single case of infection of reptiles and snakes in particular by any subspecies of coronavirus.

What should be done so as not to get sick?

Precautions must be taken if you plan to travel abroad or have recently returned from China. In the official WHO Twitter account there are published cards with recommendations. So, during the flight you should not come into contact with people who have symptoms of acute respiratory viral infections, wash your hands often or use alcohol gel / antiseptic hand wipes, and try not to touch your face with your hands. In case you find yourself having a fever, cough and shortness of breath, experts recommend immediately seeking medical help and tell your doctors about the countries you have visited recently.

Coronavirus treatment

Meanwhile, Chinese doctors managed to develop an effective method of treating pneumonia, the source of which was a new coronavirus. We are talking about extracorporeal oxygenation, in simple words, the saturation of blood with oxygen. The patient was a 53-year-old resident of Hubei Province. On January 1, he felt unwell, turned to the doctors. His body temperature was at the mark of 39 degrees for several days, and conventional therapy did not give positive results. Since his lungs were severely affected by the virus, they were connected to an extracorporeal membrane oxygenation apparatus, after which the patient’s well-being improved. If the virus is not detected during repeated tests, the man will be discharged.

Researchers from around the world are closely watching what is happening and trying to learn as much as possible about new coronavirus. The Chinese authorities, in turn, are doing everything necessary to prevent the further spread of 2019-nCoV, so we keep monitoring the situation.

Dazzling space view of earth’s aurora: lights and stars competing for glory

Dazzling space view of earth's aurora: lights and stars competing for glory 96
The International Space Station shared beautiful photos of the aurora on the surface provided by NASA.

People may already be in awe when watching the gorgeous aurora from the ground, but the International Space Station (International Space Station) recently shared photos of the aurora taken from space. It is even more more beautiful. A dazzling green light is seen above the vast surface of the ground, which complemented the golden light on the ground and the stars in the distance, like a super large light show.

The International Space Station shared 4 beautiful pictures of aurora over the surface on Twitter on January 24 . These photos are from the web photo album opened by NASA on Flickr.

As you can see from these photos, a very conspicuous green aurora appears between the city lights and the twinkling stars. Among them, the aurora and lights in the upper right photo are the brightest.

That photo was taken when the International Space Station was moving over Romania. The lights in the photo are from cities in Sweden and Finland, and the black area between these two Nordic countries is the Baltic Sea.

Aurora usually appears close to the North and South Pole. Those that appear near the North Pole are called the Northern Lights, and those that appear near the South Pole are called Southern Lights. Aurora can be seen more clearly at night, but they are actually caused by the sun.

NASA explained that when a solar storm comes towards the earth, some energy and tiny particles will drop below the magnetic field lines of the earth’s magnetic field at the north or south pole and enter the earth’s atmosphere.

These particles interact with gas molecules in the upper atmosphere, causing the gas molecules to release photons, which in turn produces beautiful aurora. If these particles touch oxygen, they will emit green and red aurora. If the interaction is nitrogen, the aurora will appear blue and purple.

Scientists – It is much colder today than in the last 8,000 years

Scientists - It is much colder today than in the last 8,000 years 97

Undisputed temperature reconstructions from around the world show that for much of the Holocene (last 10,000 years), the planet was much warmer than it is today.

Kenneth recently wrote how many new studies of glacier and sea ice sizes show that Iceland is 2-4 ° C colder today than it has been in the past 8,000 years. Only the late 19th century was a little colder.

This post was posted on WUWT and the author provided additional graphics there from other parts of the world showing that the early Holocene was warmer around the world.

First, South America, which shows 100 years ago that it was much warmer from the 1930s to the 1950s than it is today:

Scientists - It is much colder today than in the last 8,000 years 98

Next, we have a 7000-year reconstruction of the Canadian Arctic temperature:

Scientists - It is much colder today than in the last 8,000 years 99

Note that, as many of us already know, the Arctic was much warmer in the early Holocene than it is today.

Finally, let’s take a look at the Swiss Alps, which are 9,000 years old:

Scientists - It is much colder today than in the last 8,000 years 100

Here we see that today it is very cold in the Alps compared to the early Holocene. Old tree trunks found under the glaciers confirm this.

A WUWT reader added that he has “a lot more of this type of graphs, which show very clearly that the whole wolrld has been much warmer for much of the last 10,000 years than it is now.”

And there are really a lot of them!

Medieval warm period, confirmed by hundreds of works

Sebastian Lüning’s remarkable and outstanding Medieval Warm Period reference map, shows hundreds of climatic reconstructions from this period. There we find a lot of research that shows that there is nothing unusual about today’s climate compared to what it was 1000 years ago.

Here are 80 charts from 58 peer-reviewed articles showing the same.

Polar vortex: “wild” winter is coming in the US, Northern Europe and East Asia after the 16th of January

Polar vortex: "wild" winter is coming in the US, Northern Europe and East Asia after the 16th of January 101

In the upper atmosphere above the North Pole, experts saw a rapidly swirling vortex of cold air that could bring severe frosts to the United States, Northern Europe and East Asia. Serious cold snap and snowy weather are expected after January the 16th.

Snowfalls and a cold snap hit South Korea since the start of 2021, hitting historic snow maximums and temperatures. In the country, for the first time since 1964, television and newer communications are sending people cold snap warnings:

The situation is similar in Japan, where a new snow storm hit historic highs:

On January 7, the thermometer In Beijing dropped to -20 degrees Celsius, breaking the 1966 record. In other regions of China, the temperature is also not sugar, and you can only move around in special uniforms:

The cold even reached Taiwan, where the temperature in some areas dropped below freezing point, snow poured down and people realized that rice terraces can be used as a ski jump:

Even more snow went to Spain, where on January 6, 2021, a temperature of -34.1 ° C was recorded – the lowest on record. After that, a snow storm hit the country, which has not been seen for 80 years:

The same thing happens in Canada and in the northern states of the United States:

It seems that after a stratospheric warming, the subpolar vortex began to split:

The vortex itself is a standard phenomenon. However, this time experts were surprised at his movement. It is possible that in the near future it will be divided into two parts. 

Scientists associate the strange behavior with the changed climate in the Arctic, which has become warmer. From September to December, the amount of ice cover decreased significantly.

The polar vortex is a low-pressure region located in the stratosphere and filled with cold air. When the jet stream of air that holds the vortex weakens, the low pressure area moves south. 

As the ice shrinks, more moisture will move inland. It will turn to snow, so snowfalls are expected. Snow, in turn, reflects heat, leading to a cold snap.
